The essence of SP6003, the predictive timing
circuitry, is based on several U.S. patented
technologies. This assures higher rectification
efficiency by a) eliminating high cross conduction
current under all operating conditions and b)
significantly reducing the body diode conduction losses
in the synchronous rectifier.
The IC is sensitive to large supply voltage ripple. If
the IC drives a MOSFET with significant input
capacitance, Ciss, the ripple due to gate drive energy
transfer can create large ripple. Therefore, it is most
suitable to add a high frequency decoupling ceramic
capacitor of 0.01μF~0.1μF between Vdd to ground, and
the capacitor should be placed as close proximity to the
driver as possible.
